Application filed February 25, 1929. Serial no. 342,393.

My invention relates to wire screen moulding construction whereby the same may be used in manufacturing ,window and door screens.

The main object is to provide a screen moulding whereby by sawin kerfs an-dby using other suitable woodworking machinery a detachable bead member is formed having an edge projecting beyond the edge of the main body portion a distance approximately equal to the thickness of one saw kerf; to pro- .vide a screen moulding with a detachable secured bead member formed by saws and using other suitable machinery whereby before the bead is detached, the same has an edge extending beyond the edge of the main body portion, but when the bead is replaced in its proper position the same will conform to the dimension of the rabbet that was formed in defining the bead member; to provide a screen moulding whereby the construction of the same will permit any forms of frame joint connection; to provide a screen moulding with a detachable secured bead member that is economical to manufacture, eliminates theuse of surplus material, minimlzes waste material and produces a more efficient use or function, all producing a well made durable substantial screen moulding of pleasing appearance.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein give In the drawing wherein like reference characters indicate like or corresponding parts:

Fig. 1 illustrates a front elevational' view showing a w1re screen frame, winpartially dow cas ng, and window in their cooperative relationship;

Fig. 2 is a sectional view on line 2 -2 of Fig. '1, illustrating the method whereby the screen frame is adapted to slide withln the window casing or frame;

Fig. 3 is a perspective view showing the conistruction of the moulding in detail form; an

- Fig. 4 is an end viewshowing a modified construction of screen moulding.

Heretofore in screen frames the edges of the wire screen were first secured to the face of the frame members by tacks and then an individually formed bead member was placed and secured covering the ed es of the screen, this resulting in time and la or of the individual operations of measuring and fitting and securing the bead to the members comprising the screen frame. Due to poor tting and securing the bead to the frame members, and in addition to the effects of shrinkage and warpage, depending of course on the atmospheric conditions, produces, as is commonly seen, a window or screen door of unsightly appearance. Not only this, but at times a bead of different kind of wood is used to secure the wire'screen to the frame members, and when a stain and a transparent cover coat is. applied to the same, difi'erent' coloring results, due of course'to the chemicals and textureof the wood.

A method of screen moulding construction of a later design developed whereby by sawing kerfs into a strip of material a detachably secured bead member was formed in cooperative vrelationship with a rabbet and by whichthe bead member could be easily detached by the use of a sharp tool as a knife or the like, and replaced in the rabbet after the edges of a wire screen had been previously secured in the rabbet.

My'invention deals with a construction of' a screen moulding similar to the last described method of constructiombut differs in the essential respect that the bead member is formed having anedge projecting beyond the edge of the main body' portion of the moulding approximately equal to the thickness of a saw kerf, thus providing when the bead member is detached,.wire screen inserted in the rabbet, the width of the bead member will conform to the width of the rabbet, thus the rojecting edge of the bead member will be ush or even with the edge of the main body portion of the moulding. The resultsof this achievement prevent a crack from otherwise appearin in the face side of the moulding proper w en the head is connected to same.

viously the screen moulding members 1 may be secured together using any suitable joint construction and may further comprise a of course depending on the shape of the opening or casing into which the screen framej f's to be fitted. As shown the WlDdOW'jSCIn is fitted below the window sash 2, although it is to be understood that the screen frame may extend to the full height of the casing. The exterior edges of the window screen A are provided with longitudinal grooves 3 which may be of any desired but suitable shape, and which cooperate in functional relationship with the guide members 4 which are of a corresponding contour as the grooves and which are secured to the inner walls of the window casing B by the brads 5. A space indicated at C is provided between the guides "4 and grooves 3 to allow for easy sliding of the window screen and also for any expansion of the same during damp weather.

As clearly illustrated in Fig. 1 the window screen A is adapted to be disengaged from casing B by sliding the same upwardly in front of the sash 2 a distance sufficient to clear the upper ends of the guide means that are secured to the casing. .It is to be understood that the window screen may be provided with any suitable means whereby it is possible to ad ust or secure the screen within the window'casing or frame, sucli as by using hinges, slide bolts, buttons, etc.

As illustrated in Figs. 2 and 3 the numeral 6 indicates the bead member that is detachably secured to the main body portion of the screen moulding. Obviously the face side of the bead member may be of any suitable design.

Thebead is formed to be detachably secured to the main body portion of the moulding by the right angular saw kerfs 7 and 8 in such a manner that kerf 7 extends-a slight distance beyond as indicated at 10 and in proximity to kerf 8 so that a weak junction or joint 9 is formed; the same being .adapted to be cutby a sharp tool such as a knife or the like when it is desired to detach the bead from the moulding preparatory to securing a wire screen therein. The main object'of sawing kerf 7 beyond kerf 8 is to insure that as clearly illustrated in Fig. 2 and further, 1

the joint 9 will be cut entirely through when it is desired to detach the bead.

It is to be understood that the invention lies in an article having the longitudinal edge 11 of the bead extending beyond the edge 12 of the main body portion of the screen moulding a distance approximately equal to the thickness of the kerf 8, thus allowing. when the bead is detached, a wire screen 13 secured in the rabbet by tacks 14 and the bead is replaced and secured by brads 15 the width of the bead will fit or conform to the width of the rabbet; thus the edge 11 of the bead will be flush with edge 12 of the mouldin there happened to be left a ragged or splinframe consisting of three or more members, i

is cut, the edge is a apted to fit mto the groove to equalize the depth of the rabbet and hence the bead may be sli htly lower than the face surfacing the moul ing.

To counteract this difiiculty, I have shown in Fig. 4 a modified construction of a moulding whereby the bead is further provided with the edge 8' extending beyond the face surface of member 1, a distance a mumately equal to the thickness of kerf i less the thickness of a wire screen; thereby when the bead is detached and properly replaced and secured in the rabbet the edge 8' will be substantially flush with the face surface of the moulding.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to beunderstood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

'1. In an article of the character described, a moldingepiece having one surface edge extending yond the marginal face of the mold with a transverse saw kerf artially severmg the said extended portlon from the body, with another saw kerf arranged at an angle to the first kerf and extended toward the same to provide a thin joint connecting the proximate meeting edges of the two kerfs, whereby upon severing the joint the extending section will be released and may be moved backward to bring the extended edge into ris thereof to define a. detachablysecured bead portion of which a part projects beyond the edge oi the body a distance substantially equal to the width of the kerf whereby upon detaching and replacing the bead, the same. may be adjusted. flush with the edge of the b0 y member.

3. A molding comprising two'mem'bers detachably secured together of which a portion of one extends beyond the confines of the other a certain distance whereby upon removing and positioning the one, the same will be within the confines of the other.

In Witness whereof, I hereunto subscribe nggname this 30th day of January, A. D.
